    Abstract
  • <p>Given the difficulty in identifying and extracting exploration information in covered areas, the search for porphyry copper deposits faces significant challenges. </p></sec><sec><title>Objective

    The ore bodies in porphyry copper deposits are primarily low-grade metal sulfides, and further research is needed to determine the depth and extent of these deposits via gas geochemistry.

    Methods

    Preliminary experiments were conducted in this study using a portable gas analyzer for H2S and SO2 geochemical measurements at the Pulang porphyry copper deposit.

    Results

    The results indicate significant H2S and SO2 geochemical anomalies above copper mineralization, suggesting the method's efficacy in revealing hidden ore bodies and predicting their strike and dip extensions.

    Conclusion

    Areas showing good synergistic behavior, continuous anomalous concentration distributions, and potential for mineralization are promising targets for exploration. This approach represents an effective method for mineral exploration in covered porphyry copper deposits, offering new insights into prospecting concealed mineral resources.
